Unformatted text preview: Poplation Genetics : How does a population evolve? Outline: 1. Key concepts 2. Individuals dont evolve, populations do 3. The Hardy-Weinberg Theroem 4. The microevolution and natural selection 5. Genetic drift 6. Gene flow Key concepts: Individuals of a population have the same number and kinds of genes In a population, a gene may exist in different forms Microevolution means that changes have occurred in a populations allele frequencies Allele frequencies can change through mutations, gene flow, genetic drife, nonrandom mating, and natural selection Individuals Dont Evolve, Populations Do Population Is a localized group of individuals that are capable of interbreeding and producing fertile offspring Polymorphism traits come in two or more distinct forms Gene pool pool of genetic resources that, in theory, is shared by all members of the population The Hardy-Weinberg Theorem The frequencies of alleles in the gene pool will remain constant unless acted by other agents...
